I'm almost ashamed to admit that dipping my toes in PowerShell for the first time was *almost* fun! *shudders*

Ah, and to expand a bit on the "Windows 10" requirement: it's actually PowerShell 5+, which *can* find its way to older Windows versions, but *may* require manual intervention to do so (I honestly have no idea, Windows Update is hell). You can always try: the script will safely abort if PowerShell is too old.
EDIT: Reworded macOS/Linux instructions because of exec bit trickery. -_-".
